Killeen Mini Split Installation — Flat $1,500 for a Single Zone

Updated September 2026

Central Texas summers don't negotiate. If you're trying to cool a garage workshop off Trimmier Road, a converted ADU near Fort Cavazos, or a back bedroom in an older Killeen home that the ductwork never really reached, a ductless mini split is usually the cheapest fix that actually works in August heat.

ATX Mini Split King publishes flat prices instead of hiding them behind an estimate visit: $1,500 for one zone, $2,500 for two, $3,500 for three — materials and labor included. Our own TDLR-licensed contractor handles the work, most 1-3 zone jobs finish the same day, and we test the system before we leave. We cover Killeen, Harker Heights, Copperas Cove, Belton, Temple and the surrounding Bell County towns.

Why we're the cheapest published price in Killeen

Ductless mini split installation runs $2,000-$5,000 per zone nationally, and the reason that range is so wide is that almost nobody publishes a number. Local HVAC contractors, big-box store install programs and national chains are quote-based / call for pricing, so a Killeen homeowner can't compare anything until someone has been out to the house and written up an estimate. We took the opposite approach: the price is on this page before you dial. $1,500 one zone, $2,500 two zones, $3,500 three zones, materials and labor in — no upcharge games, no 'while we're in the attic' add-ons. A published flat price beats a quote because you can budget against it, and because we can't quietly move it once we see your driveway.

Frequently asked — Killeen

How much does a mini split cost in Killeen?

With us it's a flat $1,500 for one zone, $2,500 for two zones, and $3,500 for three zones, with materials and labor included. For comparison, ductless installation averages $2,000-$5,000 per zone across the industry, and most Killeen-area options — local HVAC contractors, big-box install programs and national chains — are quote-based / call for pricing, so you won't see a number until after an estimate visit.

Who is the cheapest mini split installer in Killeen?

We publish the lowest 1-3 zone prices we're aware of for Killeen and Bell County: $1,500 for a single zone, all in. We can't compare ourselves to a competitor's number because typical providers don't publish one — they're quote-based / call for pricing. What we can say is that our price is fixed, printed here, and doesn't move after we look at your house.

Can you install a mini split in a Killeen garage or ADU the same day?

Usually, yes. A garage or ADU single zone is $1,500 and most 1-3 zone jobs finish in one day. We run the system and confirm it's cooling before we leave, and if the mount or line-set penetration scuffs the wall, we'll make a Home Depot touch-up paint trip — that's included, not an add-on. Garage conversions and ADUs are some of the most common jobs we do around Killeen and Harker Heights.

Do you serve the rest of Bell County, and do older Killeen homes need special work?

We install throughout Killeen, Harker Heights, Copperas Cove, Belton, Temple, the Fort Cavazos area and nearby Bell County towns. Older homes here often have undersized or missing ductwork in additions and back rooms, which is exactly where ductless shines — no duct runs, one small wall penetration, and a room that finally holds temperature through a 100-degree Texas afternoon.
